2005-2014 Mustang ABS HCU, Pump and Electronic Module Identification

PROVEN CHAINS ONLY: 4R3Z-2C215-AA / 6R3Z-2C215-A -> 7R3Z-2C215-B; Shelby 7R3Z-2C215-A -> 7R3Z-2C215-C; 4R3Z-2C219-AA -> 6R3Z-2C219-A; Base/GT 7R3Z-2C219-B -> 7R3Z-2C219-D; Shelby 7R3Z-2C219-A / 7R3Z-2C219-C -> 7R3Z-2C219-E; early-2010 AR3Z-2C219-A -> AR3Z-2C219-C; BR3Z-2C215-B / CR3Z-2C215-A -> ER3Z-2C215-A; BR3Z-2C219-A -> BR3Z-2C219-C; CR3Z-2C219-A / CR3Z-2C219-B -> CR3Z-2C219-C. No successor is asserted for early-2011 BR3Z-2C215-A, and no AR3Z-2C219-B -> AR3Z-2C219-C arrow is asserted. A supersession inside one Ford catalog branch does not erase VIN, build, Base/GT-versus-Shelby, ABS/traction/AdvanceTrac, connector, port or configuration checks.

Start with both VINs/builds and verify that the recipient was originally four-wheel-ABS equipped; Ford's 2005 owner guide expressly labels ABS and Traction Control if equipped. Keep the 2005-2009 ABS/traction-control generation separate from 2010-2014 AdvanceTrac with TCS and ESC. For 2007-2009, never substitute the Base/GT 7R3Z-2C215-B / 7R3Z-2C219-D branch for Shelby 7R3Z-2C215-C / 7R3Z-2C219-E. Resolve both 2010 controller production branches and the 2011-08-16 HCU break by VIN/current Ford catalog. The checked Ford procedure identifies the electronic controller as 2C219, the HCU as 2C215, four controller screws, one electrical connector, two master-cylinder inputs and four wheel-circuit outputs. Require exact-item photos of both labels, connector keying and pins, all six ports and their orientation, pump motor, valve body, bracket, tube retainers and every included fastener. Require donor VIN/build/trim, stored ABS/AdvanceTrac DTCs before removal, test method, warranty and returns. Reject flood, water, fire or collision exposure; cracked or impact-damaged castings; bent, cross-threaded, uncapped, contaminated or corroded ports; fluid contamination; corroded pins; broken latches; cut wiring; unexplained opening or mixed HCU/controller halves. A warning light alone is not diagnosis: qualified testing must first exclude wheel sensors, tone rings, wiring, grounds, power supply and network faults. A replacement electronic module requires Ford-compatible as-built configuration and scan-tool calibration; a vendor's no-reload claim applies only to repair and return of the unchanged original unit. Do not infer that electronic separability permits an in-car no-bleed shortcut: follow the vehicle-specific Ford procedure. Opening the hydraulic circuit requires clean specified fluid, every tube returned to its original port, correct bleeding and qualified post-repair DTC, ABS, traction and stability verification. Provide no bypass, delete, calibration-hack or road-test-at-the-limit instructions.

Checked alternatives are exact-number refurbished electronic controllers and repair-and-return services for the vehicle's original controller. Repair-and-return can preserve the original configuration, but no-programming language is a vendor claim limited to the unchanged original unit and does not apply to a donor controller or HCU. Refurbished replacements still require exact Ford branch, VIN/build, connector and port verification and Ford-compatible configuration/calibration where directed. No checked aftermarket source proves a universal 2005-2014 HCU, Base/GT-to-Shelby interchange, 2009-to-2010 generation interchange, hydraulic bypass or stability-control delete.

2C215 identifies the hydraulic HCU/pump side and 2C219 the attached electronic controller; seller use of ABS module does not prove which is included. Verify both VINs/builds, original ABS equipment, 2005-2009 versus 2010-2014 system generation, Base/GT versus Shelby branch, exact labels, connector and all six ports. Replacement electronics require Ford-compatible as-built configuration/calibration unless a qualified repairer returns the unchanged original unit. Opening the hydraulic circuit requires contamination-controlled qualified brake service, correct line placement, bleeding and post-repair ABS/traction/stability verification. Seller prices and stock are dated observations, not guaranteed checkout fulfillment.
